Oral Spermidine Supplementation Preserves Submandibular Gland Function After Radiotherapy: Mechanistic Insights and Use in a Phase II Randomized Clinical Trial

MedComm, Volume 7, Issue 8, August 2026.
Radiotherapy‐induced xerostomia severely impairs quality of life. Integrated multiomics, organoids, murine models, and a randomized Phase II trial identified spermidine as a key radiation‐responsive metabolite. Oral spermidine preserved salivary gland function, maintained acinar cell integrity through Golgi‐mediated posttranslational modifications ...

Hierarchically Biporous Wick Vapor Chamber With Micro/Nano Condenser for Exceeding 600 W/cm2 Heat Dissipation

Small, Volume 22, Issue 44, 7 August 2026.
An integrated vapor chamber couples a hierarchically biporous copper wick with a micro/nano‐textured superhydrophobic condenser to form a self‐sustained liquid–vapor loop. The device dissipates extreme heat fluxes above 600 W/cm2, even when the condenser is above the heater, by overcoming the permeability‐capillarity trade‐off in conventional vapor ...

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, Volume 7, Issue 4, August 2026.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Unveiling the AcSirt2‐FOXO‐Mitophagy Axis: Insights Into Mitochondrial Quality Control and Delayed Aging in Apis cerana

Aging Cell, Volume 25, Issue 8, August 2026.
Age‐related downregulation of AcSirt2 impairs mitochondrial homeostasis in old bees. AcSirt2‐mediated deacetylation of FOXO enhances transcriptional activity, upregulating antioxidant enzymes (SOD, CAT) and promoting PINK1/Parkin‐mediated mitophagy. This pathway facilitates autophagosome formation and clearance of damaged mitochondria, reducing ROS ...

HNRNPC Succinylation Influences the Neurodegeneration of Alzheimer's Disease Through YME1L1‐Mediated Mitochondrial Metabolism

Aging Cell, Volume 25, Issue 8, August 2026.
In Alzheimer's disease, SIRT5 downregulation enhances TRIM25‐mediated succinylation of HNRNPC at K50, increasing its stability. Stabilized HNRNPC upregulates YME1L1 expression via an m6A‐dependent mechanism, leading to OPA1 hydrolysis dysregulation, mitochondrial fission‐fusion imbalance, ROS overproduction, and neuronal death.
